| 摘 要： | 通过北黄海盆地4口井中6个样品的测试分析,对该盆地中生界的油-源进行了详细对比和原油成因分析.经过轻烃组成、饱和烃和芳烃的色谱、质谱、饱和烃碳同位素等地化参数类比,进一步明确了产于下白垩统的原油来源于上侏罗统陆相淡水型、以Ⅱ2型为主的生油母质形成的烃源岩.同时,地化参数表明,白垩系原油属于带环烷型特征的近石蜡型原油,是具有高蜡低硫、低钒镍比、保存条件较好的陆相成熟原油.

| Abstract: | Oil-source correlation and origin analysis have been carried out in Mesozoic of the North Yellow Sea Basin based on tests of 6 samples from 4 wells.Correlations of geochemical parameters such as light hydrocarbon composition,chromatogram and mass spectrum of saturated and aromatic hydrocarbon,and carbon isotope of saturated hydrocarbon have indicated that crude oils in the Lower Cretaceous mainly come from the continental fresh water and Ⅱ2 type source rocks in the Upper Jurassic.The Cretaceous crude oils are similar with the paraffin ones,characterized by naphthene.They are continental mature crude oils with high wax and low sulfur contents,low alum/nickel ratio and good preservation condition. |
